Original May 12, 2017:More classical world-conquering is coming our way, as Europa Universalis IV is expanding again with Third Rome, due “this spring.” It was announced during the PDXCon press conference today, and will focus on Russia.

The above trailer was also shown though it doesn’t give you a lot more info. The description calls it an “immersion pack” and promises to build on the “incredible depth” of EU4.

“The pack focuses on building a deeper experience for Russia and its cultural brothers,” reads the description, “introducing new means to wield spiritual, political, and military control in the Russian empire.”

Here’s the feature list, via Paradox:

Tsardoms and Principalities: New ranks of Russian government with new abilities and, for Tsars, strong bonuses including the right to claim entire States – not just provinces

Iconography: Commission great religious icons for the Orthodox Church, boosting your empire’s power depending on the saint you choose to revere

Patriarchs: Consecrate highly developed provinces with Patriarchs, adding to the authority of the Orthodox Church, but for a cost.

Streltsy: Special Russian soldiers that excel in combat, but raise the cost of stabilizing your empire
